Abstract
The concept of federated e-identity is gaining attention worldwide in light of evolving identity management
challenges to streamlining access control and providing quality and convenient online services. In a
federated system, participant institutions share identity attributes based on agreed-upon standards,
facilitating authentication from other members of the federation and granting appropriate access to online
resources. The article provides an insight into the ongoing federated e-Identity initiative in GCC countries.
The aim of the initiative is to develop a trusted and secure cross-border infrastructure to authenticate and
validate citizens' identities across GCC borders. Such an interoperability platform can then be used to
facilitate citizens' mobility and stand as the basis for digital economy development. Current literature does
not include any information about the work being conducted within GCC countries in relation to the GCC
eID platform. This article thus contributes to developing a better understanding of such practices, triggers

1.Introduction
The field of identity management systems has been evolving rapidly over the last
two decades [Al-Khouri, 2012]. With this development, countless modern systems have
been introduced, many of which are innovative and are based on breakthrough sciences
[Bertino and Takahashi, 2010; Williamson et al., 2009]. The technological evolution,
associated with increasing customer expectation in relation to service quality and
convenience, has created a higher demand for more integration between such systems
[Bhargavan et al., 2008; Cabarcos, 2013; Camenisch and Pfitzmann, 2007; Novell, 2011].
Concepts such as service oriented architecture; online government and new public sector
management are pushing the field of practice to establish digitally trusted and federated
identities for individuals that can be used across borders by service providers in electronic
environments [Buecker et al., 2005; Chadwick, 2009; Goodrich et al., 2008].
On a global scale, the field of identity management has witnessed a significant
number of initiatives to address this requirement, often referred to as federated identity
management systems [Baldoni, 2012]. These initiatives have been grappling with
providing services such as single sign on and identity verification capabilities to enable
seamless identity management solutions. These implementations vary in terms of the
frameworks they follow and the trust mechanisms they use.
Governments have been realizing the need to develop interoperable federated
identity management platforms to support citizens' mobility cross-borders [Bruegger,
2007; Fleurus et al., 2011; Langenhove et al., 2011; Porter, 2008]. The European
Commission is implementing a project to develop an interoperable electronic
identification [eID] platform to provide a single, secure, and cross-border infrastructure
for the authentication of legal and natural persons across Europe [STORK, 2013]. GCC
countries1
are also working on a similar platform development to facilitate GCC citizens’
mobility and to enhance economic cooperation between the six member states. Both
1
GCC stands for Gulf Cooperation Council, also called the Cooperation Council for the Arab States
of the Gulf (CCASG), which was established in 1981 to promote coordination between member states in economic and
social spheres. It includes six countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates.
The GCC population is estimated to be around 40 million.

projects aim to allow citizens to access cross-border services securely by using eID
credentials issued by their home countries.
The objective of this article is to provide a high level overview of how GCC
countries intend to develop an interoperable identity federation across their countries. The
existing literature does not include any information about this subject, and this study will
attempt to fill in some fundamental knowledge gaps in the existing body of knowledge.
This should, in turn, trigger debate and discussion, open the door for reflection and
subsequently guide international efforts in this eminent domain of practice.
The article is structured as follows. In section 2, we present the various dimensions
of federated identity management systems and the platform on which such systems are
designed. In Section 3, we elaborate on the identity federation and present the critical role
of an identity provider in the overall federation ecosystem. In section 4, we present the
current conceptual and agreed design of how identity federation across GCC countries
will operate. In Section 5, we reflect on the differences between the GCC interoperability
framework and the European STORK 2.0 project. We also reflect on the necessity to
address and meet the needs and expectations of the customer spectrum in order to
increase the chances of success of such large and mission-critical endeavors. The article
is then concluded in section 6.
2.Federated Identity Management Landscape
Sharing identity information and enabling access to different resources has always been
an issue within multi-service, single channel delivery environments. If we consider the
Internet to be the channel of service delivery, multiple service providers and content
providers exist. These providers use their individual user management and identity
management systems to enable user access to the services, resulting in multiple logins
and multiple identities for users. This is not only inconvenient but also inefficient. This is
far more complex as compared to an enterprise in which the organization accords a
singular identity.
Managing and handling identities in a typical Web model is more complex on
account of multiple domains as opposed to a single domain in the enterprise. Identity
federation provides just the right and effective mechanism for handling these issues.
Federation literally means “united in an alliance.” “Identity Federation” is thus the
mechanism by which a group of members, who form a union, collaborate on identity
information.
Identity federation describes the technologies, standards, and use-cases that serve to
enable the portability of identity information across otherwise autonomous security
domains [CNIPA, 2008]. The ultimate goal of the identity federation is to enable users of
one domain to securely access data or systems of another domain seamlessly and without
the need for completely redundant user administration [ibid.].

4.
International Journal of Public Information Systems, vol. 2013:1

Page | 23
The use of an identity federation has the potential to reduce costs, enhance security,
and lower risk by leveraging stronger credentials to enable an organization to identify and
authenticate a user once and then use that same identity information across multiple
systems, including external partner systems [Manish and Sharman, 2008]. It can arguably
improve privacy compliance through identity authentication and authorization controls
and drastically enhance the citizen experience by eliminating the requirement for
multiple registrations through automatic "federated provisioning" [Blakley, 2010].
The term "identity federation" is, by design, a generic term and does not refer to or
imply any specific implementation technology. An identity federation can be
implemented in any number of ways. Liberty Alliance, WS-Federation, and Shibboleth
are examples of different frameworks and initiatives leading to trust establishment
between different service providers. These address various identity verification and
authentication development capabilities. See also Annex-1 for more elaboration on these
frameworks. On the whole, many current systems are based on open standards and
specifications, but there are many other frameworks and approaches in existence that are
proprietary.
On the other hand, there are also many technical vocabularies and terms commonly
used in every identity federation discussion. The general components that make up any
federated identity management systems are depicted in Figure 1. The next section
elaborates on the components.
Figure 1. Identity Federation Consideration
2.1. Identity Provider [IdP]
An IdP is an entity that issues an identity to an individual or an entity and manages user
authentication and user identity relevant information. It plays a key role in not only

5.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 24
providing a digital identity but also in authenticating the user and storing attributes about
the user. Potentially, an identity provider offers the following:
1. Identification and authentication data: This can be used to inform the service
provider who the user is and the identity provider guarantees that it is really that
user.
2. Authorization data: This is meant to ensure that the user is allowed to perform a
specified operation.
3. Personal profile details of the entity: If the identity holder permits it, this is based
on a request from a service provider.
2.2. Service Provider [SP]
An SP [also referred to as relying parties] is an entity that offers services to users who
seek any services based on the eligibility and provision of the services for users/service
seekers. It basically provides services to the user and relies on the identity provider to
perform user authentication.
2.3. Service Seeker
A service seeker is an identity holder and an entity that seeks services for an individual or
for group consumption from a service provider. This could be a person, a group of
people, an organization, a process, or even a device—i.e., any subject that is able to make
a transaction [servers, network devices, and people]. The user interacts by using agents,
such as a browser, with a service provider’s online application and seeks a service.
2.4. Digital Identity
This is the electronic representation of the identity of an individual or an entity within a
given applicable domain. This identity is, generally, a combination of different identifiers
and credentials packaged for use in electronic transactions.
2.5. Identifiers
Identifiers are different attributes of a given digital identity. These compose the metadata
related to a digital identity and constitute an identity profile [e.g., unique identity number,
certificates, name, and date of birth, address, or employment details].
2.6. Credentials
Credentials are a set of objects/elements that serve to authenticate an identity by means of
the validation of its identifiers. This follows the [1] what does one know? [2] What does
one have? [3] What is one’s identity? For example, credentials can be a password or a
valid response to a challenge, constituting what the individual knows. A credential could
be a digital certificate constituting what the individual has. Finally, a credential could be

6.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 25
an inherent characteristic of the entity, such as a fingerprint, eyes, or voice. This defines
what the individual is.
2.7. Domain of Application
This is the application scope in which the digital identity has validity [e.g., a government
department, company, hospital, club, university, or the Internet]. An individual may have
several identities/roles within the same domain of the application. For instance, a doctor
could become a patient in the same hospital where he/she works. A doctoral research
student could double up as a lecturer in a University.
2.8. Circle of Trust
This is a trust relationship between involved stakeholders. Organizations that have built
trust relationships to exchange digital identity information in a safe manner preserve the
integrity and confidentiality of the user’s personal information.
2.9. Single Sign-On [SSO]
This allows users to authenticate with an identity provider and then gain access to
different services provided by several service providers with no extra authentication.
2.10. Assertion
This is a piece of data produced by a security assertion markup language [SAML]
authority that refers to an act of authentication performed on a user together with
personal profile data as required. This assertion completes the circle of trust.
Having described the components of a federated identity management, the next
section presents the fundamental role of an identity provider in the overall federation
ecosystem.

3.The Role of Identity Provider in the Federation
Ecosystem
Figure 2. Federated Identity Eco-System
An identity provider plays a pivotal and key role in the overall identity management
process [see also Figure 2]. In the context of multi-organizations, the identity provider’s
role then becomes more crucial. For the overall ecosystem to operate successfully, trust
must be established between service providers and the identity provider, both of which
are required to reach an agreement on the trust mechanisms, enabled by the latter, in
relation to the offered identification and authentication capabilities. Cross-domain
identity management systems, by design, delegate the identification and authentication
role to the identity provider. Service providers typically manage their own identity
management systems, which determine the eligibility, accessible privileges, and the
overall authorization functionality. Figure 3 illustrates how, on a high level, an identity
federation and its management fit into this scheme.

8.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 27
Figure 3. Roles of Identity Providers
An identity provider typically follows three processes that establish the identity of an
entity [human or machine]. These are as follows:
4. Enrollment Process: Registration of the entity, collecting various identifiers, and
storing them for later verification and validation.
5. Digital Identity and Credentials Issuance: Credential generation, packaging the
identifiers and credentials, and issuing the Identity for Assertion.
6. Authentication Capabilities: Verification and validation of credentials and
identifiers and establishment of the identity of an entity.
Identity federation management focuses on rationalizing these three processes with
respect to managing the identity lifecycle, such as creation, update management, usage,
revocation, and facilitation of the unification, sharing, or linking the digital identities of
the users among different service providers across different application domains.
From a legal standpoint, governments have long been the de facto identity providers
through the issuance of identity documents to their citizens and residents—e.g., passports,
ID cards, driving licenses, voter registration cards, and more. With the advancement of
the Internet and remote service delivery, trust and identity assertion in the digital
environment has become an urgent requirement. Coping with such pressing needs,
governments, the world over, have realized the need to modernize their identity
management systems and initiate technologically-driven, digital identification
infrastructure development programs that create digital identity profiles together with
various electronic identifiers and credentials.

9.
International Journal of Public Information Systems, vol. 2013:1

Page | 28
If we consider this to be the basis for an identity federation, interoperability should
be an easier exercise. Modern government identity programs in GCC countries fully fit
these requirements and are compliant to all the design requirements of an interoperable
and federated identity that can be used across borders. We further elaborate on this in the
next section.
4.Identity Federation in GCC
All GCC countries have initiated modern national identity management programs during
the last ten years. Each country issues smart chip-based identity cards that are associated
with the advanced technologies of public key infrastructure and biometrics [e.g.,
fingerprints, iris scan, and facial recognition]. Identity management systems in GCC
countries are backed by independent national identity legal frameworks.
Technologies and systems that constitute the digital identity in GCC countries are
similar and are based on a similar set of identifiers and credentials. Figure 4 depicts the
advanced capabilities provided by the smart identity cards in GCC countries.
Figure 4. National ID Card as the Enabler of the Digital ID
In addition, smart cards in GCC countries are equipped with advanced functionalities
that address digital transformation requirements, which include the following features:

8. Establish a person’s identity on-site, remotely allowing secure and trusted
transactions.
9. Multi-factor authentication capabilities provide both match-on-card and match-
off-card features and facilitate validation, verification, and authentication of an
Identity.
10. The cardholder is accorded all identity services—validation, verification,
authentication, and assertion of identity—from the respective national identity
providers.
This, indeed, serves as a reliable platform to establish trust between different entities
cutting across borders. Figure 5 depicts a generic framework adopted for digital identity
issuance, identity services, and the overall identity lifecycle management in GCC
countries. It depicts the different layers that compose the current national identity
management framework in each of the GCC countries.
The government is at the heart of the framework—the first, innermost layer—
because GCC governments have realized the need to own the development of their digital
economies through the development of digital identities. This is also based on the belief
that a government-issued digital identity is likely to provide higher levels of trust and
assurances, and would have a positive impact on the uptake and usage by service
providers. Each of the GCC countries has established independent entities and
departments to act as an identity authority [identity provider], which provides the second
layer of the framework. These entities and departments are responsible for the
development of the infrastructure and provision of identity services [i.e., authentication
and validation services].
These are layers three and four. Service providers and citizens make up the fifth and
sixth layers, respectively, as beneficiaries and users of the identity services. Identity
lifecycle management creates the seventh layer and represents the integration platform
with other government organizations in order to maintain automated data updates in those
cases involving changes to personal data.

Figure 5. National Digital Identity—the GCC Context
In 2012, GCC governments initiated a large-scale project to make their national
identity cards recognizable—digitally—across borders. Technically speaking, this should
not be a difficult endeavor. The building blocks for an interoperability platform between
GCC countries already exists in their national digital identity systems as they are based
on common international standards and quite similar technologies.
Each of the GCC countries has set up a national validation gateway to provide
authentication and validation services to both public and private sector organizations in
their own countries. These gateways are designed to provide a federated identity for
government-to-government and government-to-citizen transactions. For instance, when a
user moves from one service provider to another, the assertion token is released to the
second service provider, who trusts the authentication token generated in the first place.
This ensures that, across multiple service providers, the same authentication token can be
used to trust the service seeker/user without the need for the user to login or self-
authenticate multiple times.
In the e-government context, this token could be handed over to the e-government
portal, and the e-government entity acts as the identity proxy. Figure 6 depicts how the
national validation gateway has been set up in the UAE.

12.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 31
Figure 6. National ID Card and Federated Identity
The GCC federated identity management concept is based on extending the services
provided by national identity providers to the GCC bloc, in which each identity provider
will act as a proxy for any of the others. This will serve to bridge the identity providers in
a seamless bind for individual digital identity holders across the identity providers. An
authentication carried out by an identity provider in the UAE, for example, can be passed
on as a “token” to the identity provider in Oman. The national validation gateway in
Oman will then determine whether to grant or revoke access to the service or resource.
See also Figure 7.

13.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 32
Figure 7. Federated Identity in the GCC Context
It is here, in this context of interoperability, that an identity federation in the GCC
countries becomes a crucial cog in the interoperability wheel. When this is extended to
the GCC, the identity providers in other countries are accorded with the “Assertion”
token [which is essentially a SAML token] from the home country [e.g., the UAE identity
provider]. See also Figure 8.
Figure 8. GCC Federated e-ID
Efforts are already underway and the GCC countries have conducted multiple
workshops on interoperability. Pilots are in the planning stage to ensure “recognition” of
the ID cards using Web services. In fact, a common API was developed in 2011 to read
public data, in offline mode, from the GCC smart identity cards and this has been
implemented at borders [airports and land and sea ports] in each of the six countries.
The current working phase links the national validation gateway systems in all
countries to provide online validation and verification services across borders. Figure 9
depicts a high level, tentative implementation plan of the GCC eID interoperability
project.

5.Reflection
5.1. GCC e-ID Interoperability Platform vs. European STORK 2.0
If we disregard the fact that there is still no formal charter document for GCC e-ID
interoperability, the main difference, in relation to the European STORK and STORK 2.0,
is in the current approach to interoperability. The federated eID is highly dependent on
the existing national identity systems in GCC countries, through which identity validation
is performed across borders. In essence, the overall objectives are the same as the
STORK and STORK 2 objectives. Figure 10 depicts these objectives.

15.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 34
Figure 10. Key Objectives of STORK and STORK 2.0
From a technical perspective, the GCC interoperability initiative is conceptually the
same as the European initiative. The main differences lie in the approach and
implementation. See also Figure 11.
Figure 11. GCC interoperability schema
GCC eID interoperability is driven by national identity management systems, from a
vision that identification and credentials issued by governments are central to
interoperability. However, the current GCC project scope is still narrow and focuses on
cross-border identification and credential verification as its principle priorities.

16.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 35
This prompts us to recommend that GCC governments broaden their visions on how
such an interoperable eID platform will address more strategic future opportunities and
how it can support the overall transformation of GCC countries and the development of
sustainable digital economies.
5.2. Addressing the User Spectrum
Figure 12. Pillars for successful federated identity management systems
Key to the development of a workable federated identity management system is in
meeting the needs and expectations of the customer spectrum—i.e., users and service
providers, who are the ultimate beneficiaries of such systems. One of the creative, yet
simple, models that we recommend is Kano's Model, also depicted in Figure 13. The
main objective of this model is to assist organizations to understand the three categories
of customer needs and attributes so that new products or services can be launched
successfully. The model classifies product attributes based on how they are perceived by
customers and their effect on customer satisfaction [Kano et al., 1996]. These
classifications are useful for guiding design decisions in that they indicate when good is
good enough, and when more is better [ibid.].

17.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 36
Figure 13. Kano Model of Customer [Consumer] Satisfaction
In principle, the model addresses three quality categories [also called Critical To
Quality Characteristics [CTQs]]:
 Dissatisfier – Must have – This is the absolute basic requirement that the
product/service must meet. Without this, the customer will surely be dissatisfied.
 Satisfier – More is better – This defines improvization in the basic requirements
or better performance in the basic requirement. These factors will enable the
customer to be satisfied.
 Delighter – Meeting the latent need – These factors are differentiators. They
bring delight or the “wow” factor to the customer.
See also Figure 14.

18.
International Journal of Public Information Systems, vol. 2013:1
www.ijpis.net
Page | 37
Figure 14. Kano Model
The identity federation is required to be designed on such a quality basis. In a
federated identity management project, it is imperative to define the service specifications
based on the needs and expectations of our citizens and reach out to the delight levels at
both ends of the customer spectrum. Governments must focus on creating added value.
Federated identity can bring significant value and can enhance online education systems,
healthcare management [eHealth], government and public services, and overall IT
infrastructure transformation. See also Annex-2.
The potential value of an Interoperable eID between countries is enormous. If
designed with clear and concrete milestones and measurable outcomes, GCC countries
will not only enhance their national security but will also take giant steps toward the
development of a true knowledge-based, digital economy [Al-Khouri, 2012; Landau and
Moore, 2011].
6.Conclusion
As indicated, it is certain that the benefits of a single PAN GCC digital identification and
authentication area scheme are legion and will require the current economic cooperation
between GCC countries to reach new and higher levels. A GCC eID interoperability
platform should allow citizens to establish and conduct e-transactions across borders,
merely by presenting their national eID issued to them from their own home countries.

19.

Page | 38
Cross border user authentication has the potential to create benefits in different sectors
and enhance access to educational resources, commercial transactions, and banking
transactions. The possibilities are endless.
GCC governments will still be required to work with each other so as to formulate a
legal framework that sets the rules and defines how identity providers, service providers,
and users will interact and the overall framework in which identity verification and
validation services will operate. They will be required to broaden their visions and
collaborate more closely in order to address future challenges and opportunities. An
interoperable eID platform can, indeed, place GCC countries at the forefront in the digital
economies arena and global competitiveness.
As a final note, interoperability will certainly become a precondition backbone for
future development efforts at all levels. As the world appears to become smaller and more
ubiquitously connected [with landscape geography having no meaning], countries and
governments will require to act as one entity. A global eID platform will be an attractive
objective in the near future. In fact, in the years to come, interoperability will become
more associated with global sustainability; they will be two sides of the same coin. This
will be a conundrum many will seek to solve for years to come.

frameworks based on this principle of collaboration and the sharing of identity
information. Their initiatives are aimed at establishing trust between different service

methods based on open standards and use the SAML Assertion. The following is a brief
description regarding each of the three frameworks.
 SAML is the foundation for all of the current identity federation mechanisms. It
has passed through three releases: 1.0, 1.1, and [the most recently ratified] 2.0.
SAML 2.0 is seen as a point of convergence as it incorporates Liberty Alliance’s
ID-FF 1.1 and 1.2 specifications as well as Shibboleth version 2 functionalities.
 Shibboleth is a 'single-sign in' or logging-in system for computer networks and
the Internet. Shibboleth is a project of Internet2/MACE and seeks to develop the
architecture, policy structures, technologies, and open source implementation to
support inter-institutional sharing of Web resources. This is, of course, subject to
business rules and access controls that will allow inter-operation. This initiative
seeks to provide peer-to-peer collaboration using a federated identity
infrastructure based on SAML. Shibboleth has been largely adopted by university
and research communities around the world. Shibboleth 2.0, which was released
in March 2008, is based on SAML 2.0.
 The Liberty Alliance is an organization of vendors and enterprises that is largely
perceived as having been formed in response to Microsoft’s Passport efforts.
Since that beginning, the Liberty Alliance has written several protocols, enabling
both browser-based identity federation as well as a Web services identity
federation. The Liberty Alliance protocols include the identity federation
framework [ID-FF] and identity Web services framework [ID-WSF]. Their ID-FF
work, which originally resulted in two versions of the ID-FF specification, has
now been incorporated into SAML 2.0. The Liberty Alliance has also taken on the
role of certifying conformance and interoperability of vendor products to
federation standards. They provide testing services for SAML 2.0 as well as for
their own protocols.
The Liberty Alliance project has released its specifications for Identity Federation
as open technology standards and guidelines for federated identity management.
The guidelines include privacy protection and describe the requirements for
handling identity information. The Liberty Alliance specifications include Identity
Federation Framework specification for single sign-on, federated account linking,
identity provider introduction, and global logout. It also defines messages and
protocols for securing Simple Object Access Protocol [SOAP].
 The WS-* Federation started as a proposal from IBM and Microsoft to define how
companies could share user and machine identities across corporate boundaries
and across domain authentication and authorization systems. It defines a security
framework for Web services and has developed a full suite of specifications
driven by a collaborative effort among Microsoft, IBM, VeriSign, RSA Security,
Ping Identity, and others.

Some of these protocols, such as WS-Security, have been submitted to and ratified
by existing standards organizations, such as Organization for the Advancement of
Structured Information Standards [OASIS]. WS-* can be thought of as a suite of
specifications for enabling secure Web services. This collection of specifications,
including WS-Trust, WS-Federation, and WS-Policy, is an evolving set of
mechanisms for layering authentication, authorization, and policy across both
single and multiple security domains.
Open ID
OpenID is a newer, “open, decentralized, free framework for user-centric digital
identity” 3. OpenID is designed for users who desire a single login for several
applications on the Internet. The framework is driven by the needs of Web 2.0
applications such as blogs and wikis. OpenID has a much more lightweight nature
and is not based on several layers of XML schemas, WS-* standards, or a variety
of data formats and communication channels.
Whereas these latter specifications amount to several hundred pages, the OpenID
specification is only 14 pages long. One could say that the other specifications
satisfy an organization’s wish to provide advanced functionality and fine-grained
control. Instead of using SAML to create identity assertions, OpenID uses the
eXtensible Resource Descriptor Sequence. This metadata format utilizes
eXtensible Resource Identifiers [XRIs] to identify users. After authenticating with
an OpenID Provider [OP], the XRIs are validated by the OpenID Relying
Partners[RP] before permitting access. Typically, the RP will host an
authentication service that refers the user back to the selected OPs when first
accessing the Web site. In essence, the OpenID mechanism does not appear to be
significantly different to a SAML or WS-Federation use case.
Annex-2: Examples of the potential impact of
an international, interoperable eID on different
sectors.
 Healthcare Management: Providing access to healthcare services and insurance
with a single identification and authentication. Healthcare has a huge potential
when viewed in terms of electronic health [e-Health] [World Health Organisation,
2010; see also Linkous, 2009]. Telemedicine, as a concept, necessitates remote
access and authentication. This is virtually non-existent today. Major healthcare
centers, such as existing government hospitals in GCC countries, can potentially

associate with American/European partners in providing telemedicine facilities
that can be driven by the identification and federated authentication of the patients
[e.g., in accessing patient records]. The global growth rate in telemedicine is
estimated at 19% [Digitome, 2011]. A population of over 380 million in the
MENA region in 2013 [two thirds of which is rural] at a cost of $385 per patient
per year translates to $97.5 billion. Only 10% of this population is taken in
relation to telemedicine— working out to nearly $10 billion. There are many
other economic impacts that Telemedicine could create: e.g., saving on
transportation costs, time, and manpower, none of which have been considered in
the calculations. Telemedicine will be extremely useful and cost effective when
applied to the correctional institutions for the inmates. In terms of security, no
transportation means no potential jail breaks, and secure identity ensures the
prevention of fraud in health. There are many advantages.
 Online Education: Enhancing access to educational materials for students across
universities. Online education is expected to grow at a healthy rate of 26%
annually [at a conservative level]. Considering the growth in population and the
skill sets required, very few universities are available and online education is
even lower, at the present time. If we consider that the Middle East will require
55 million skilled employees in the next 10 years, even if only half of these are
catered for, the current education facilities will not be sufficient. The opportunity
window, in this case, is huge in terms of providing quality education online, and
this requires strong identity management—specifically, identity federation—so
that students are able to gain access to worldwide resources. Thus, American
universities, for example, can provide access to the learning material based on
enrollment at local universities [see, e.g., European Commission, 2005; Kapoor,
2011].
 Government Services: Improve access to government services. Digital signature
services for remote transactions are expected to exceed $15 billion in the
immediate future [with land deals and property transactions and e-enabled goods
and services]. Regarding e-Government services, with consideration only being
given to the UAE and KSA, the e-Government payment transactions were
published at a value of 4.7 billion AED and 2.8 billion SAR for 2012 and 2011
[Dalakian, 2012; Rorissa et al., 2010]. Estimates of G2G, G2B, and G2C can be
facilitated by using the national ID card. The potential is huge.
 IT Transformation: Identity As A Service [IdAAS] will be the cornerstone of IT
transformation across the region, enabling the migration of conventional IT
systems to cloud computing. The value of this transformation, in pure economic

terms, is estimated at $5 billion globally in the next five years. Cloud services are
on the rise in the Middle East. As per market estimates, cloud services are valued
at a staggering $462 million in 2013 in the MENA region and are estimated to
grow at 18% annually [Gartner, 2013]. The world market today is estimated at
$131 billion [Whittake, 2013].
